NITED STATES AVERY VAN WIE, OF INDIANAPOLIS, INDIANA, ASSIGNOR OF ONE-IIALI T BENJAMIN B. BO OTH, OF SAME PLAOE.

GATE-LTCH i SPECIFICATION forming part of Letters Patent N. 140,092, dated November 4, 1890.

Appiication filed Iebrnary23, 1889. Sera1 No 300,991. (No model.)

T0 aZZ whom it may concern.-

Be it known that I, AVERY VAN WIE, of Indianapolis, county of Marion, and State of Indiana, have invented certain new and 5 usefu1 Improvexnents in Gate-Latehes; and I do hereby deelare the following to be a full, clear, and exact description of the invention, such as WIII enable others skilled in the art 130 which itappertains to make and use the same.

My improvement relates to that class of Iatches in which the hook 0r bolt is adaptecl to be held in proper position by gravity.

'lhe objects are t0 produce a gate-latch that shall be efficient, durable, and eheap; and

with these ends in view my invention consists in certain parts and form in construction, as

. will be more fully shown, described, and

pointed out in the following drawings specifications, and claim.

In the drawings forming part of this specification, Figure 1 is a sde view of the letch in engagement with its keeper. Fig. 2 is a front view of the latch end keeper (IS attaehed t0 gate anc post.

2 5 a in the construction of the gate-Iatch is a bracket, whichissecured firmlyto the gate gby means of screws c, which pass through e1011- gated slots, Which letter allow of its vertieal adjustxnent. a is also provided with two para11e1 projections,to end between the extremities of whieh is loosely pivoted the rotary gravity hook 01 latch b at Z2 dis the pin or stop, over which the rotating hook catches. This pin is provided at f 5 with a tapering screwsection, and has formed at e en angu1ztr section, adapting it to be turned byawrench,so that it may be screwed very tightly into the gate-post h, which is broken away in the drawings to show seid 0 screwsection. b has forrned at 1) a, fingerheld, by which this rotating hook is turned fro1n its engagement with the stop d when it is desired to open the gate. 19 is also provided with a convex surtaee at Z9 which is adapted t0 strike against the pin obliquely at a point 5 cl, as here shown, by which ineens the rotating hook K) is more gradually started (0 revolve when closed. The impulse thus received by this hook causes it to make a complete revolution upon its axis b in the direcdon of the arrow, so that when the movement is complete the hook engages With the pin,as seen at d, Fig. 1. This rotating hook is retained in very nearly the position seen at Fig. 1 when unlatehed. Henee for the hoek te be c0me unlatched accide1itally from the efiect of recoi1 due to the gate being closed t00 rapidly is a matter of impossibility, as the 1atch would have to return onethird of a revolution or more asrainst the effect of gravity to become nnlatched.

In the application of this1atch the pin might be placed on the gate and the rotating hook on the post without chan ging the prineiple of action.

Havi-ng thus fu11y described my invention, what Iclairn as new, and desire t0 secure by Letters Patent, is

In a gate-latch, the combinttion comprised of a pin 0r stop hzwing a pointed screwthreaded section and an anguiar section by which said screw-section may be easily driven into the post, and a revolving and gravitating hook loosely pivoted in a vertieaily-adj ustable support secured to the gate, a11 sub stantially as specified.

In testimoy whereof I subscribemy name in the presence of two witnesses.
